Several variants of papillary thyroid cancer have been described, including, most recently, Warthin-like tumor of the thyroid gland. To bring attention to this uncommon variant, we review previous reports on this entity and we add 5 new cases to the literature. We retrospectively reviewed the records of all patients who had undergone thyroidectomy at our institution during a 7-year period. Among these cases, we identified 5 patients who had had a Warthin-like tumor of the thyroid. From their charts, we compiled data on age, sex, lymphadenopathy, distant spread, and treatment. Pathologic specimens were reviewed for tumor size, capsular invasion, and vascular invasion. All 5 patients were women (mean age: 51.6 yr). Tumor size ranged from 0.9 to 2.0 cm. Multifocality was seen in 1 of the 5 patients; this patient was also the only one who experienced capsular and vascular invasion. No patient had lymph node spread or distant metastasis. Because the follow-up period among these patients was still short, we were unable to analyze long-term survival data.
